2 Claims. 1

This invention relates to a card for the mounting and protecting of hypodermic needles and similar units.

It is an object of the invention to furnish a support or card by means of which a needle may not alone be retained and protected, but by means of which the needle will be displayed in a manner such that a person desiring to use a needle will be able to select one of proper dimensions Without it being necessary to open the assembly or card.

A further object is that of furnishing a card or mounting for hypodermic needles and combined with the needles in such a manner that the latter will be retained in association with the mounting without there being any danger of accidental detachment of the parts occurring.

Among other objects are those of providing a unit of this type which may embrace any desired number of assemblies capable of being readily detached from each other and each serving to support the needle in a manner such that its point will remain undamaged while at the same time danger of injury to the operator's fingers will be avoided. Moreover, a unit of thistype may be manufactured at nominal cost and by quantity production methods.

With these and other objects in mind reference is had to the attached sheet of drawings illustrating one practical embodiment of the invention and in which:

Fig. 1 is a perspective View of a card and showing hypodermic needles in association therewith;

Fig. 2 shows the strip or card in open position and with no needle mounted thereby;

Fig. 3 is a face view of a card with a needle contained or mounted thereby;

Fig. 4 is an edge view of the unit as shown in Fig. 3;

Fig. 5 is a sectional side view taken along the lines 5-5 and in the direction of the arrows as indicated in Fig. 3; and

Fig. 6 is a transverse sectional View taken along the lines 66 and in the direction of the arrows as indicated in Fig. 3; such view being on slightly enlarged scale.

As shown in the several views 6. The interveningopposed faces I3 may be recessed or inwardly curved to a maximum depth at points intermediate their side edges. Conveniently the faces I! are provided with indicia as indicated at I4 which may show the gage of the needle and any other desired information. This indicia may, of course, be continued throughout the lower surface of the hub.

Extending from the end of thehub is a cannula l4 pointed at its end as indicated at [5. This unit provides the needle proper and is secured to V the hub against displacement. As is well understood this assembly is placed in association with the barrel of a hypodermic syringe so that the epidermis may be pierced and medicament injected. In this description a more or less conventional type of needle has been traversed. As will be appreciated this is merely illustrative and needles of other outline and structures might be employed except Where otherwise indicated in the claims hereafter.

The mounting card has been shown in flattened or open condition in Fig. 2. Preferably it includes a strip l6 of suitable flexible material such as paper. This strip is provided with a substantially central line of fold H. Adjacent each of its ends amain opening 18 is furnished and the outline of which preferably corresponds in gen eral terms to the outline of the hub as heretofore described. The opposed side edges [9 of this opening are spaced a distance less than the maximum width of the needle hub. Preferably they should be substantially equal to the minimum distance between the base or most recessed portions of the curved faces I3. Into at least one of the openings I8 a tongue portion 20 extends and which is integral with the body it of the strip. Likewise that body in line with one of the openings is formed with a further opening or window 2|.

Preferably a number of these cards provide the body of a main card. This has been shown especially in Fig. 1. The several strips or subsidiary portions may be initially joined to each other and defined by rows of perforation or scoring 22. Obviously along those lines one strip may be separated from the others by simply exerting a bending or tearing action. Also as shown especially in Fig. 1, it is preferred that one leg of the strip It be longer than the other leg. In this manner an extended portion 23 exists which permits the operator to readily separate the layers if the strip is simply folded upon itself as aforedescribed. It will likewise permit a ready separation of the layers should the card be com- 'posed of separate strips adhesively or otherwise the openings is. Under these circumstances the cannula or needle M will lie against the inner surface of that layer or strip portion. The second layer is brought to a position superposed with" respect to the first layer and so that the hub portion of the needle also extends through that second opening. Therefore, as shown, the needle part will be effectively housed. Also, the indicia 14 upon the faces i2 and other portions of the hub will be adequately displayed. Additionally, due to the Windows or sight openings 2! the person inspecting the assembly will be able to see the cannula.

With the distance between the edges I9 being less than the overall maximum width of the needle hub it is apparent that as shown especially in Fig. 6'these edges will cam against the hub sur- T face so that the superposed layers of the card will bernaintained in close-proximity to each other. That assembly will also be maintained by the tongue portion 20 whichpreferably has a Width. equal to the diameter of the hub bore. Therefore, the layer of which tongue 28 forms a part will be maintained centrally of that bore.

In use, all that an operator Will have to do is to detach one of the cards or strips from the main body of the assembly. Thereafter, by simply grasping the exposed edge portion 23 of one layer it will be possible to separate the layers with facility- This willbe because of the flexible-nature of strip 15 Which will allow of such separation. At the same time the needle will remain associated with one of the layers so that there will be no danger of the needle becoming com-. pletely dislodged and dropping with possible damage to its point or other portions.

Thus, among others, the several objects of the invention as specifically aforenoted are achieved. Obviously, numerous changes in construction and rearrangement of the parts might be resorted to without departing from the spirit of the invention as defined by the claims.

I claim: a

1. A mounting for a hypodermic needle including in combination a needle comprising a hub having a pair of opposed recessed, axially extending faces and a cannula mounted by said hub, a flexible strip folded upon itself and presenting in its superposed layers openings for the accommodation of said hub with the cannula extending in housed relation between said layers in the direction of the fold, the width of said openings being substantially equal to the distance between the bases of the recessed hub faces, whereby contact between the edges of the openings and said faces will retain the layers against accidental separation withrespect to each other and said hub, at least one of said layers being formed with a further opening, said further opening being aligned with the cannula.

2. In combination a hypodermic needle comprising a hub having an axially extending mouth and axially extending recessed faces and a cannula extending from and secured to said hub, a flexible strip folded upon itself and presenting in its superposed layers aligned openings defined by edges extending in the direction of said fold, said edges being spaced a distance less than and engaging the base portions of opposed faces of said hub to thereby act as detents in cooperation therewith and prevent accidental separation of said layers, the distance between said openings and the line of fold of said strip being greater than the length of said cannula and the latter extending between said layers in the direction of said line of fold, a tongue forming a part of one of said layers and projecting into the mouth of the hub and such latter layer having a length greater than that of the adjacent layer to extend beyond the same and terminate in a manipulating portion.
